Technical Field

The utility model relates to a plant cultivation field, concretely relates to use U type pipe in the compound infiltration of throat is ventilative device plays the orientation to draw the root, play the device that the accurate confession fertile water supply supplies the medicine for plant (trees).

Background

Trees growing in severe environments or newly planted areas such as sidewalks, motor vehicles and non-motor vehicle isolation belts, parking lots, poor drainage, grassy tree contradictions and the like, such as fallen leaves and evergreen trees of Chinese scholartree, goldenrain tree, white wax, ginkgo biloba, Chinese pine, white bark pine and the like, are poor in tree growth due to soil hardening, undersize growth pits and the like, and particularly under the continuous condition of abnormal weather, the growth vigor of a plurality of trees is reduced, even a part of trees are dead, or the trees fall down and the disease and pest outbreak phenomenon occur.

In view of the above problems, the inventor of the present invention discloses "application of narrow tube effect to Beijing garden plants" in "Beijing garden" 2016 (2 nd stage) of Weijia bear and pandepin, which is introduced in the text: through systematic studies of ancient trees, big trees, and the like, it is known that: the weak growth vigor of ancient trees and big trees on the ground is mainly caused by the phenomena that the underground environment, namely the root system growth environment, is badly changed, the water infiltration is difficult, the gas exchange in the soil is difficult, and the leaves of street trees are reduced, become yellow and the like in normal seasons, so that the weak growth vigor is caused; the authors invent a composite water and air permeable device by using the narrow-tube (bernoulli) effect, and the device is partially applied in the daily maintenance, planting and rejuvenation processes of garden trees;

the processing method comprises the following steps of (1) punching: selecting a position close to a road tooth and far away from the trunk of a tree needing rejuvenation, such as an ancient tree, as far as possible; vertically perforating, wherein the aperture is 40cm, and the depth is 100cm, (2) placing an outer layer tube: placing an outer layer pipe with the inner diameter of 11cm into the hole, and keeping the outer layer pipe level to the ground level; (3) putting an inner layer U-shaped pipe: placing the treated inner layer pipe, wherein the height of the inner layer pipe is 5 cm lower than that of the outer layer pipe; the U-shaped pipe comprises a thick side pipe, a thin side pipe, two side pipes and a bottom pipe, and the bottoms of the thick side pipe, the thin side pipe and the bottom pipe are communicated; (4) filling a mixed matrix: filling a prepared substrate (special substrate for the growth of ancient trees and big trees) outside the outer-layer pipe, and filling the substrate with a tool; then, after the pipe orifice of the inner layer pipe is temporarily blocked by a plug, the gap between the inner layer pipe and the outer layer pipe is also filled by the matrix; in the process of filling the matrix, the matrix is tamped by a tool; after filling, pulling out the plug, and covering the inner layer pipe and the outer layer pipe by using a green cover; the materials form the composite permeable breathable well;
